I have used the site quite a bit over the last year and have finally sifted through Canadian and American coins and kept aside some interesting (to me) ones that I have a few questions about. So since this is my first post here, I'll just say "HI" and figure out where to post questions and pics. (Unless of course anyone wants to help direct me to the next step. :)).
Ok, I'll give you a suggestion as to where to start. Pick out your best few Canadian and US coins and post them in the respective grading forums. Good places to generate some interesting opinions and convo.
